“Why the I.R.S. Should Go After Trump”

The New York State attorney general yesterday filed a lawsuit against the Donald J. Trump Foundation and its directors, accusing the charity and the Trump family of violating campaign finance laws, self-dealing and illegal coordination with the presidential campaign. It asks that Mr. Trump pay restitution and be prohibited from leading a nonprofit in New York for 10 years.

As a former attorney for the chief counsel of the I.R.S. who specialized in nonprofit organizations, I believe Mr. Trump is also criminally liable for his actions. If I were still at the I.R.S., based on the lawsuit, I would make a criminal referral, on charges of tax evasion or false statements on a tax return, or both.
